Translucency of 3D‐Printed 3Y‐ and 5Y‐Doped Zirconia
Journal of Esthetic and Restorative Dentistry, EarlyView.ABSTRACT Objectives To evaluate and compare the translucency of 3D‐printed zirconia materials: 3Y tetragonal zirconia polycrystal (3Y‐TZP) and 5Y partially stabilized zirconia (5Y‐PSZ). Material and Methods 3D‐printed 5Y‐PSZ and 3Y‐TZP materials fabricated using digital light processing (DLP) were investigated.

Effect of yttria inclusion on room temperature tensile properties of investment cast TiAl
, 2018 Yttria is the best face coat material in the shell mold for the investment casting of γ-TiAl alloys. However, yttria inclusions may occur in the cast products and there is a lack of knowledge about the influence of yttria inclusions on the mechanical ...

Journal of Esthetic and Restorative Dentistry, EarlyView.ABSTRACT Objectives This study evaluated the effects of material and surface condition (glazed vs. polished after simulated occlusal adjustment) on translucency parameter, contact angle, and flexural strength of four monolithic zirconia. Materials and Methods Disk‐shaped specimens (n = 80, Ø12 × 1 mm) were fabricated from four monolithic zirconia ...

Journal of Esthetic and Restorative Dentistry, EarlyView.ABSTRACT Introduction Patient‐reported outcome measures (PROMs) remain limited in prosthodontics, including for ceramic resin‐bonded fixed partial dentures (RBFPDs), despite their growing relevance in minimally invasive practice. Oral health–related quality of life (OHRQoL) can be reliably assessed using the validated Oral Health Impact Profile −14 ...

, 1977 Fourteen samples of 99.999% Y/sub 2/O/sub 3/ were melted near the focus of a 250-W CO/sub 2/ laser. The average value of the observed melting point along the solid--liquid interface was 2462 +- 19/sup 0/C. Several of these same samples were then melted in ultrahigh-purity oxygen, nitrogen, helium, or argon, and in water vapor. No change in the observed
